What to do
Water recreation access: At SacWest RV Park & Campground, visitors can enjoy river access and family-friendly facilities. "One of the better parks I've visited... I parked in the back along the river which was ideal with grassy spots along the river and campfire spots to use," notes one camper.
Wine tasting trips: The Lodi wine region is accessible from Flag City RV Resort, providing an opportunity for day trips. "Clean and safe overnight stop along I-5... We'll likely stop here again when on our way somewhere," mentions a visitor who appreciated the convenient location for regional exploration.
Ferry access to San Francisco: Camping at Marin RV Park provides ferry access to San Francisco. "Drive in, park and then walk to all the sights you want to see in San Francisco. A short 10 minute walk from the RV park is the ferry that will drop you off downtown San Francisco," shares one camper who used public transportation during their stay.
What campers like
Waterfront sites: Campers at Rio Viento RV Park appreciate the riverside location. "Beautiful, quiet clean dog friendly park with very nice helpful staff. Large brick sites," notes a visitor, though they caution "road to get into the park is rough but take your time."
Pool and recreation areas: Several parks offer swimming pools and recreation facilities. At SacWest, "Pool, game room, wifi, SHOWERS!😍💞" mentions one enthusiastic reviewer, while another notes the abundance of wildlife, saying it's "Serene and full of fowls."
Dog-friendly amenities: Flag City RV Resort earns praise for pet accommodations. "Squeaky clean and organized... AND HUGE fenced area to walk your dog OFF LEASH," writes one pet owner who considered this amenity exceptional enough to "give this place 6 stars if I could!"
What you should know
Site spacing concerns: Many parks feature closely spaced sites. At San Francisco RV Resort, "Spots are tight. Staff is great! Laundry hot tub pool are always clean. Right on the ocean (on a cliff)!" explains one camper, while another mentions "Most rigs have an excellent view of their next door neighbors slide out."
Variable road conditions: Several campgrounds have challenging access roads. Rio Viento visitors consistently note the rough entry road, with one stating "The only issue I had which has nothing to do with the park is the road leading into the park is extremely [bumpy]."
Seasonal allergies: Certain campgrounds have specific allergen concerns. At SacWest, "The campsites are directly located under mulberry trees. They triggered severe hay fever symptoms in me," warns one visitor with seasonal allergies.
Tips for camping with families
Off-leash pet areas: Several campgrounds accommodate pets with designated areas. At Flag City RV Resort, one visitor praised their "HUGE fenced area to walk your dog OFF LEASH" as a standout feature for families traveling with pets.
Kid-friendly activities: Look for campgrounds with recreational options. "Lots of things to do for kids: great playgrounds, swimming pool, more than 100 ducks going around!" reports a family staying at Sugar Barge RV Resort & Marina, which also offers "kyacks and have a restaurant that looks right over the water."
Tent options: While most sites cater to RVs, some offer tent camping. At Sugar Barge, "The tent-area was a clearing, fully backed up to the levee, with some shade and a water spigot. Appears to be only 4 'sites,' which are defined by picnic tables, GENEROUSLY spaced, no fire rings."
Tips from RVers
Big rig accessibility: Several parks can accommodate larger rigs. At San Francisco RV Resort, "This RV park gets 5 stars purely for it's location... It truly is nothing more than a parking lot with hookups," notes a visitor who prioritized location over spaciousness.
Cell coverage details: Reception varies significantly by carrier. At Flag City RV Resort, "We got 4 bars on Verizon" reports a camper who stayed in January 2024.
Hookup configurations: Rio Viento visitors praise the site designs with "Very nice large sites with large grass areas," though one visitor notes "water spigot is really close to the ground and really close to the sewer drain. Scrub with bleach before booking up your water and you'll be fine."
